The Pond Guy InstaFix Algae Control, Outdoor Water Garden, Fountain & Birdbath Algae Solution, EPA Registered Liquid Algaecide, Control Green Water & String Algae, Bird, Fish & Pet Safe, 2.5 Gal

It really clears my small pond of all the cloudiness. I started getting slime grass after the winter this year and it got thick, so I started using the liquid every 3 days and the grass has been clearing out. I am very satisfied.

This was fantastic I followed the instructions on the bucket and it cleared my pond up immediately. This is a great product you couldn't see the bottom of my pond and before I knew it the water was crystal clear and the green that was in it was gone.

I was struggling with my pond aeration pump, and algae was building fast. I may have helped the product by starting early in the algae life, but I used only a gallon (much less than recommended dose but all I had of the product) and it literally worked just like it said. That very night the pond looked cleaner, within two days it looked sparkling.

I ordered this because the string algae was out of control no matter what I did. I used this and after the first dose I started vacuuming the bottom to get all the dead algae out and after the second dose it got the sides of my pond cleared up. My pond is a 20'x 20' oval with a waterfall and the depth is from 3' near the waterfall to 4. 5' in one corner opposite of the Savio skimmer box and it has cleared it all out.

For a small outdoor pond, keeps it clean and good value for the money. Amazon too expensive, Often Walmart is cheaper than Amazon.

The water in my pond was so green I couldn't see the bottom. On Pond Guy's recommendation, we began treating with AlgaeFix and experienced a noticeable improvement in just 24 hours.

It hasn't cleared my pond yet, but I'm hopeful. It's fall, less sun on the pond, so maybe that will help too. I understand I can dose the pond every 3 days so I'll try that a couple times, no more than that.

I've used this product for years and it normally takes care of the green water. There's been no string algae, just green water, which tells me that there is algae in the water? But for some reason this has made no difference at all, this summer and I've already bought and used 2 gallons!

Has knocked down half of the string algae and duck weed. Not like your photos showing complete die off.

Sorry to say. This product doesn't work at all. Used it with a fresh, clean pond, and one that was very cloudy. (because it didn't work on the fresh, clean). It was regretably not helpful on either.
